Abstract: The purpose of this paper is to analyze the stability of closed loop switching power amplifiers using an accurate model of a loudspeaker installed in a commonly used bass reflex enclosure instead of the purely resistive model that can be used with a Zobel network. The model takes into account the electricalmechanical-acoustical parameters of the transducer as well as the voice-coil loudspeaker's non-linear behavior, avoiding stability problems when trying to compensate for the output filter stage, thus obtain…
